A method and apparatus for widening a viewing angle in a video conferencing system are provided. The apparatus for widening a viewing angle in a video conferencing system includes: generating reference data from images of a video conference participant captured by a camera included in the video conferencing system; generating movement data based on the video conference participant's movements sensed by the camera; extracting a first control parameter by comparing the reference data with the movement data; transmitting the first control parameter to the other end of the conference; receiving a second control parameter generated at the other end of the conference; and controlling the camera by the second control parameter.
